Product details

Product Description:

Direct acting self operated pressure (differential pressure) regulating valve, composed of valve body, valve seat, valve core components and other parts, is an energy-saving product that does not require external energy and relies solely on the pressure changes of the regulated medium to automatically regulate pressure. It can be used as a pressure control device for non corrosive (maximum temperature 350 ℃) liquids, gases, steam and other media. Widely applicable to industrial sectors such as petroleum, chemical, metallurgical, and light industry, as well as urban heating and heating systems.
